1. An implant, adapted to post-operatively and non-invasively be adjustable by a remote control or a push bottom under the skin adapted to activate an implanted control unit of the powered implant, comprising at least one expandable section;
wherein said implant is adapted to be adjustable between a first at least partly collapsed state, in which said expandable section is at least partly collapsed, and a second expanded state, in which said expandable section is expanded, wherein an outer surface of said expandable section at least partly comprises a surface structure having elevated areas alternating with lowered areas, wherein said expandable section is adapted to have, in said first collapsed state,
a first distance between adjacent elevated areas sufficiently extended to prevent growth of fibrotic tissue from directly interconnecting adjacent elevated areas to an extent that compromises the adjustability between a first collapsed and a second expanded state of said implant said first distance being greater than about 1.0 mm, and wherein the implant further comprisingconnecting areas between adjacent elevated and lowered areas, further adapted to have, in said first collapsed state,a second distance between adjacent connecting areas sufficiently extended to prevent growth of fibrotic tissue from directly interconnecting adjacent connecting areas to an extent that compromises the adjustability between a first collapsed and a second expanded state of said implant said second distance being greater than about 1.0 mm, wherein said implant, further comprising; at least one sealed hollow space of the expandable section adapted to receive a fluid, a reservoir adapted to hold said fluid,
a powered pump, adapted to move fluid from said reservoir to said hollow sealed space to create pressure in said chamber, andwherein the outer surface of the expandable section is adapted to be filled with a pressurized fluid, comprises said elevated areas alternating with lowered areas. |
